feat: validate combination of object type and privilege in PrivilegeDef

At the later stage I discovered that sbroad applies the same validation
rules during parsing of grant/revoke statements and even its own
Privilege enum that is a ~copy of our PrivilegeType. Unfortunately
at the moment there is no way to share code between picodata and sbroad
efficiently (now only tarantool-module is shared and it is not suitable
for such kind of things) so it still makes sense to have this in
picodata because this is the point where all APIs converge to the single
point (CaS). In the future all other ways of validation should be
removed. Aside from sbroad similar kind of validation is performed
independently on lua API side.

Note that in prior commit 45ba7392 we've
removed all privileges from role super. This patch removes privileges
from admin that do not match the model: namely all privileges on
universe except session and usage. With this patch it is no longer possible
to grant or revoke such privileges.
